high alumina light weight bricks
-High-Alumina insulation bricks
High Alumina insulation brick is a kind of insulation material adopting organic matter as ignition loss substance.
High-Alumina insulation brick has small volume density, good insulation effect,high mechanical intensity, small thermal conductivity and long service life.For various industrial kilns & furnance.
High-Alumina insulation brick is a kind of sessential refractory for energy saving and temperati\ure preservation.
High-Alumina insulating clay brick can be used auxiliary with other lining materials for the coke oven to have better insulation effect and save energy.
